Application filed October 2,1908. Serial No. 455,908.

To all whom it may concern:

Be it known that I, CHARLES TATHAM, a citizenof the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Apparatus for the Manufacture of Lead-Incased NVire or Cables for Electric and other Purposes, of which the following is a specification.

Such articlestfor example as electric wires or cables have at times to be protected by a suitable covering or casing surrounding the same. Lead has been found to be a satisfactory covering but such lead must not be so hot when applied as to injure or destroy the cable or wire for the intended use.

This inventionhas for its object to avoid such injury while allowing the cable or the like to be efiectively or-hermetically incased' or protected.

In carrying out this invention care must be taken to avoid any leaks or water becoming mingled with the lead as this would impair the efficiency of the cable.

This invention is set forth in the following specification and claims and illustrated in the annexed drawing in which is shown an apparatusfor incasing cables or the like, the cooling means passing through the ram and into the cylinder of a hydraulic press or ram, the cooling means in the cylinder being independent of and separate from the core for guiding the cable which is located at a distance from the cooling medium or the channel conducting the same. In this drawing is shown a cylinder or reservoir a adapted to contain lead- A bottom piece I) has a core 0 and a die d arranged for a wire or cable to pass therethrough. This passage (1 c is so bored or arranged that as the cable travels therethrough lead from the reservoir can be pressed about and made to incase the cable, and also be preliminarily cooled to such an extent that such lead while tightly inclosing the cable will not burn or injure the same.

A ram e'will force the lead or material about the cable passing through the passage 03 c. As the cable enters the die d and passes on and out of the apparatus the surrounding lead will form a hard or durable and flexible protection. Preliminary cooling of the lead before it clasps or contacts with the cable is eifected by a suitable medium such as water suitably applied. The ram e is carried by cross head 12 fixed on standards g operated by base 1'. The cable enters core 0 and leaves at die d and the cooling is effected by tube f passmg through the ram e. The tube has inlet 2' and outlet k and this tube f Works through ram 6 and is held in proper relative position in the cylinder by cross head 02 and upright supports 0 attached to the cylinder a.

The outer wall or shell of the Water tube f can be made free from joints or connections or allof one piece at the part which projects through the ram and into reservoir a. As the great pressure of ram e entering reservoir a is apt to cause any joint to loosen and as the consequent leak would injuriously effect 'the process such leak is to be avoided.

As seen the conduit extends axially through the ram 6 and the ram can reciprocate while the conduit remains stationary.

What Iclaim is 1. An apparatus for incasing cables or the like comprising a reservoir for containing lead,a ram to force lead from the reservoir, a bottom piece made to communicate with the reservoir and having a core and die for the passage of a cable, and a conduit for cooling medium to temper the degree of the lead as it is forced about the cable by the ram, said conduit being made to project through the ram into the reservoir and the condult in the reservoir having its outer wall closed and being separate from and independent of the core guiding the cable.

2. An apparatus for incasing cables or the like comprising a reservoir for containing lead, a ram to force lead from the reservoir, a bottom piecemade to communicate with the reservoir and having a core and die for the passage of a cable, and a conduit for cooling medium to temper thedegree of the a crosshead with movable base for carrying my hand in the presence'of two subscribing the ram and a. crosshead'supported on the wltneses. reservoir and made to support the conduit said conduit in the reservoir having its outer CHARLES TATHAM' 5 wall closed and being separate from and in- Witnesses: 1 dependent of the core gulding the (able CHRISTIAN ALMSTAEDT,
